Expressiveness and Completeness in Abstraction [PDF]
, 2012 We study two notions of expressiveness, which have appeared in abstraction theory for model checking, and find them incomparable in general. In particular, we show that according to the most widely used notion, the class of Kripke Modal Transition ...

Dams, Dams and More Dams: Issues in Evaluating Business Cases for Dam Expansion in Australia
Environmental Research Communications, 2023 Abstract Conventional interventions for mitigating flood risk and increasing water security often focus on large-scale engineering solutions despite evidence of significant cost overruns and negative environmental impacts. This study is an example of participatory research in water economics, motivated (and requested) by concerns from ...

Discharge predicted in compound channels using adaptive neuro-fuzzy inference system (ANFIS)
Open Engineering, 2023 Some hydraulic structures and phenomena, including compound channels, must be studied in relation to open channel flow. Despite the fact that the primary channel and watersheds share a similar degree of roughness, estimating discharge in composite ...
